I'm setting up something somewhat like an emailed course and using the Automated Workflow.
I'd like A/B split test some subject:'s.
I can't see where to do that.
I have gotten to this screen: http://screencast.com/t/I6v7OXVQ7bTG
And the next choice is Start Workflow but I don't want to actually startit yet, I want to define A/B tests first.
